Background:
Acinetobacter baumannii is gaining importance as a cause of nosocomial infections, but its role in skin and soft tissue infection (SSTI) is not well defined. As a result of the outbreak of A. baumannii occurring in military personnel in Iraq and Afghanistan, reports of severe wound infections and SSTI caused by this pathogen are increasing in frequency.
Methods:
We describe four cases of monomicrobial and polymicrobial A. baumannii-associated necrotizing SSTI accompanied by A. baumannii bacteremia and offer a review of similar experiences published in the literature.
Results:
Our comparative analysis reveals four unique features associated with necrotizing SSTI associated with A. baumannii: i) Occurs in hosts with underlying comorbidities (e.g., trauma, cirrhosis); ii) is often accompanied by bacteremia; iii) multiple drug resistance and the presence of co-pathogens frequently complicated treatment (64% of cases); iv) the cases reported here and in our review required surgical debridement (84% of cases) and led to substantial mortality (approximately 30%).
Conclusions:
As the prevalence of A. baumannii continues to increase in our health care system, SSTIs caused by this organism may become more common. Clinicians must be aware that the spectrum of disease caused by A. baumannii could include severe necrotizing SSTI and that vigilance for potential complications is necessary.
Insights
Acinetobacter baumannii can cause severe necrotizing skin and soft tissue infections (SSTI), often with bacteremia. High mortality rates and drug resistance complicate treatment, requiring surgical debridement.
Area of Science:
- Infectious Diseases
- Microbiology
- Clinical Medicine
Background:
- Acinetobacter baumannii is an emerging cause of nosocomial infections.
- Its role in skin and soft tissue infections (SSTI) is increasingly recognized, particularly following military conflicts.
- Reports of severe wound infections and SSTI caused by this pathogen are rising.
Observation:
- This study details four cases of necrotizing SSTI caused by Acinetobacter baumannii, with associated bacteremia.
- A literature review of similar cases was conducted to identify common characteristics.
- The infections were sometimes polymicrobial, involving other pathogens alongside A. baumannii.
Findings:
- Necrotizing SSTI associated with A. baumannii often occurs in patients with comorbidities like trauma or cirrhosis.
- Bacteremia frequently accompanies these severe skin infections.
- Multiple drug resistance and co-pathogens complicated treatment in 64% of cases.
- Surgical debridement was necessary in 84% of reported and reviewed cases.
- The mortality rate for these severe infections was approximately 30%.
Implications:
- As Acinetobacter baumannii prevalence increases, clinicians should anticipate more severe SSTI cases.
- Awareness of the potential for severe necrotizing SSTI caused by A. baumannii is crucial for timely diagnosis and management.
- Vigilance for complications, including bacteremia and drug resistance, is necessary for effective patient care.
